Hello Michael,

We have done this with a printing service that is local to us here at Dartmouth.
The cost is about $20, and the resolution is about 20 microns. Perhaps you have
a similar printing service near you?

For the procedure, please see the Dartmouth Thayer School of Engineering web
site:

Best of luck,
Craig McGray
Dartmouth College
